Multiplying Fractions?

Question

Please help me understand HOW to determine the answer for this equation. I have to understand it to use in the future. Thanks!
9/15 x 30/72 & reduce to lowest terms.

Answer 1

well first of all when you multiply fractions, you multiply straight across... so for your problem, you would multiply the 9 by 30 and the 15 by 72.

but an easier way to do this is to first reduce the fractions before multiplying them, so you would divide 9/15 by 3/3 to get 3/5, and 30/72 by 6/6 to get 5/12.

so now you have 3/5 x 5/12 which is 15/60. divide 15/60 by 15/15 to get 1/4.

Answer 2

9/15 * 30/72=

make the 15 1 make the 30 2
make the 9 1 make the 72 8

answer is 2/8=1/4

Answer 3

It's really easy; to answer this problem you must use order of operations.

1) Parenthesis 2) Exponents 3) Multiplication 4) Division 5) Addition 6) Subtraction

So... 9/15 = 0.6 30/72 = 5/12 and then you multiply the two numbers.

Answer = 0.25

It's easy to do on a calculator.

Answer 4

multiple the numerators across and the denominators across,you should have a fraction as an answer. Now divide both the top and the bottom numbers by the same number, as many times as you can until you cannot divide evenly anymore .So 9*30=270 and 15*72 = 1080. 270/1080

First I tried dividing by 10: 27/108
Then I divided by 27=1/4 this is in lowest terms

Answer 5

9 x 30 = 270

15 x 72 = 1080

reduce to 1/4
you can either do it with a calculator or use a little guesswork. in this case you divide both terms by 270.

Answer 6

first you multiply the numerators together (top numbers) ex. 9X30 is 270, then multiply the denominators (bottom numbers) ex. 15X72 is 1080.. then you put 270/1080 which reduces to .25... I hope this helps

Answer 7

270 / 1080 = 0.25
